A continuous flow contaminant removal membrane bioreactor system for LA purification using GMOs.
Production cost of high purity Lactic Acid (LA) in Green Biorefinery processes is significantly burdened by the cost of conventional purification operations. Toward a novel LA production scheme, UCD has developed GMOs that can selectively catabolize undesirable organic acids (e.g. contaminants). This study aims to develop and optimize an efficient LA purification method (using GMOs), by employing a novel continuously operating Membrane Bioreactor (MBR), wherein a biological process (contaminant removal) is integrated with a physical separation process (membrane filtration) in a single operation. Therefore, a multidisciplinary approach should be developed, taking into consideration the interrelating biological, chemical and physical phenomena involved.
The candidate will be based in CERTH, the largest R&D Centre in northern Greece and will be registered at Technische Univ. Wien (TUW). The candidate, under the supervision of Prof. A.J. Karabelas (CERTH) with inputs from Dr. S.I. Patsios (CERTH) and Prof. M. Harasek (TUW) will be trained on:
- Development of analytical tools and monitoring techniques for hybrid biological/membrane separation processes (MBR),
- Operation and process optimisation of hybrid biological/membrane separation processes (MBR),
- Key operating issues, notably membrane fouling monitoring and mitigation techniques.
